Is this right??
10 + 7 = 17/100 = 41.2 %
100 + 92 = 192/100 = 1.92 %
15 + 13 = 28/100 = 1.25 %
28 + 22 = 50/100 = .5%

I don't know what the addition problems are. However, I checked your percentage answers.
This is right.
192/100 = 1.92 %
The others are wrong.
Remember to divide the numerator by the denominator and then multiply by 100.

These can you write them out for me?
100 + 92 = 192/100 = 1.92 %
15 + 13 = 28/100 = 1.25 %
28 + 22 = 50/100 = .5%
I went through them and still came out with these answers? So confused now. I udnerstand what you mean, but it comes out the numerator so I thought they were right? Can you explain each?

Can't figure out why this one is wrong?
28 + 22 = 50/100 = .5%

28/100 = ??%
17/100 = ??%

Did you divide the numerator by the denominator?
28 divided by 100 = ?
